If you can not get at least 2.5 volts DC for the noise test voltage, then increase the Audio pot for each
channel to 2.5 volts AC on your meter and repeat the noise adjustments. You can go as high as 3.0 volts for the
audio test point voltage and still maintain good performance from the voter.
Tech Support:
Telephone technical support (410-586-2177) is available most days from 6 to 9 pm Eastern
Standard Time. Replies by FAX (410-586-8475) and e-mail ([email protected]) are also welcome and are
promptly answered.
Last Resort:
As a last resort only, LDG Electronics will attempt to repair any problems. As much as we would like to
do it for free, we just can't. We have a flat fee of $70 plus parts to repair an RVS-8 (most resistors and
capacitors are included in that fee). The 68HC11 chip is $20, the X68C75 is $30, the 34064 is $3, and the
X25040 is $5. Most of the other chips are around $1 each.
We will not attempt to repair any unit that has been soldered with acid core. We reserve the right to
refuse repair due to excessive problems or damage due to construction.
Before any unit is sent to us, you must first call to get return authorization. All units returned must be
prepaid, either by check, money order or Credit Card unless other arrangements are made. Package the unit
carefully and keep in mind we will use your packaging to return the unit to you. Include a description of what
problem you are having and a phone number you can be reached at in the evenings in case we have questions.
Repairs average about 3 to 6 weeks, depending on the particular problem.
We are investigating the possibilities of providing loaner units to prevent significant down time while
repairs are being made.
Upgrades:
We are continually trying to add more features in the software of the RVS-8. The original software was
locked in with version 1.4 at the time of the QST article (with minor changes since) and contains the features
described in this manual.
If you have an idea of how the unit can be made better (in software or hardware), please send a
description of your idea. If we use it for the RVS-8, we'll send you the “beta” version of the upgrade for
evaluation to see if it’s what you wanted. We’re currently looking at “auto failing” channels (like the GE
voters) that automatically disables any channel that fails a timeout test. Since the software is planned to be
enhanced, we will offer the first few upgrades for free. The planned upgrades will require only a X68C75 chip
exchange.
We still work on the honor system (because most of our customers are very trustworthy). We will
send you an upgraded chip first, so that your system will have the minimum amount of down time. Then, you
just send the old chip back to us to be eligible for future upgrades at no cost. If you purchased the unit from
LDG, we will notify you when upgrades are available.
